The \u003cstrong\u003e1-LD\u003c\/strong\u003e model from Armstrong features a 1\/8\" orifice capable of handling up to 121 psig, making it ideal for high‑pressure applications.\u003c\/p\u003e\u003cp\u003eThe lever‑activated float rises with water level, opening the orifice to vent pressure once the preset threshold is reached. When the water drains below the set point, the float drops, closing the valve to prevent backflow and maintain system integrity.\u003c\/p\u003e\u003ch4\u003eKey System Performance Baselines:\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Rating:\u003c\/strong\u003e Handles up to 121 psig, suitable for most commercial boiler loops.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOrifice Size:\u003c\/strong\u003e 1\/8\" inlet ensures precise flow control and minimizes water hammer.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFloat Design:\u003c\/strong\u003e Free‑floating lever provides quick response to changing water levels.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation Flexibility:\u003c\/strong\u003e Compatible with standard 1\/8\" pipe threads for easy retrofit.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e⚠️ \u003cstrong\u003eApplication Profile:\u003c\/strong\u003e Boiler condensate lines, hydronic heating loops, fire‑tube boiler systems, and high‑pressure steam condensate return.\u003c\/p\u003e","brand":"Armstrong","offers":[{"title":"Default Title","offer_id":43112708669534,"sku":"1-LD","price":268.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/1_LD_image_d6df011c-047a-478e-af7b-6746f680eb66.png?v=1785947191","url":"https:\/\/nationalboilersupply.com\/products\/armstrong-1-ld-free-floating-lever-drain-trap-1-8-orifice-121-psig","provider":"National Boiler Supply","version":"1.0","type":"link"}
